TO ALL WHOM IT MAY CONCERN:

De it 'known that I.I. F.' GEBHART, of New Albany, inthe 'county of Floyd, and in the State of`Indiana, have invented certain new and useful Improvements in Looms; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings andto the letters of reference marked thercon,making a part of this spccication. l

My invention relates to the manner of operating the hed'dle-frames'iu looms whereby any number, from two to twenty-four, may be used for weaving fancy twilled or plainA cloth.

In the annexed drawings, A represents the `ordinary frame of the loom with the sheave-frarne A elevated above it. At one end of the frame is placed a'metallic upright, connected to the upper of which arc two oblong bows, a a, which support the slides that operate thelieddle-frames. C represents a vertical shaft which extends to the tops of these bows, andrsecured upon the frame in-,front or in the rear of the metal upright which supports the bows a. This shaft has a peculiar-shaped cam, D, near its top, which is revolved with the' shaft. This cam is made of an oblong oval form, and provided with a groove,ff, fig. 3, to correspond with the shape thereof. At the top of the shaft C is a metallic wheel, E, provided with two lugshg g,-plac e'd on its circumference at opposite sides from each other, and having small' notches cut into the edge of wheel near the lugs. Pivoted to the armlof the metallic standardvare two levers, H H, which extend from their pivot t" between the bows a a, where they are rested, and connected by means of pins on their ends into the groove ff offthe cani D. These levers are each provided with a slanting flange, o o, on their outer edges, which lie between the blows a a, as seen in fig. 2, and which are intended to catch under dogs G that straddle the sliding hars F. The slides F F F are supported upon bows in the frame A and bars a ZI, and are so placed as to 'move out and in when operated bythe machinery. One of the dogs Gr is placed upon each slide sothat motion is imparted to them by the working of the levers. The dogs areforrned with a shoulder at each end at' their under parts, and are made heavier at the inner ends so'that one shoulder is ready to be caught by the innerlever as it is spread bythe cam, and then by the outer lever, aswill be more fully described. It will be observedthat the inner ends of the slidesF are bent so as to connect the straps that support the heddle-frames, while there are cords or'straps connecting the said slides which pass over the sheaves d d in theframe A' and pass towardf the bottom `under sheaves dl, suitably secured upon a standard, and thence under another slicave near the metallic standard, thence over sheaves di', secured between the bows aa, and again to the projecting eudso'ftthe slides,.so that the same motion that draws the'heddle-frames in one direction will draw them inthe other. At the top of thibows there is a small shaft, I, provided with a cog-wheel, m', on its outer end, and having a small spurwheel, n, on its inner end, which catches into the notch and against the lugs on the wheel E as it is turned 'upon its shaft AC. .K represents the pattern cylinder, having pins or lugs z 's z upon cach faceand' bearing upon the outer ends of the dogs, raising or lowering the ends of the same as it is turned, and allowing the flanges o o to catch against the slrofulders and carry the slides from the bows a a, or vice versa. YThis cylinder has a cogwheel, m, on its outer end,'and is secured between the bows by two. curved bars, y, which are provided with slots for regulating the bearing of the pins upon thedogs.

In the operation of the harness by this invention the power lis applied to the main shaft B, which has a small bevelled cog-wheel, c, on its end, which meshes into a faced cog, b, upon the lower end of the shaft C. This shaft, by means of its cam D and the pins on the ends of 'levers H H, will cause the 'levers 'tosprcad as the cam is revolved, and the flanges catching against the shoulders on the dogs G will `force the slides F out and back, drawing and withdrawing the heddle-frames by means of the cords e, arranged as before stated. As the shaft C'is revolved theV lugs g g on thc wheel E will strike the spurs on the shaft I and turn it so that the cylinder' .K is forced around enough to allow one ofthe pins to pressv down the dog and cause one slide to move outwards while the other two are moved inwards, (according to the number of slides used,) and carry the proper motion to the heddle-frames.

Having thus fully described my invention` what I claim as new, and desire to secure by Letters Patent, is

1. The arrangement of the slides F F F and dogs G, as constructed nnd used in combination withthe levers H H and com D, for the purposes speeied. I

2. The wheel E, with lugs g g, shaft I, spur-Wheel n, cylinder K, with pins z z zvfor operating the dogs G and giving motion to the slides F, when constructed and operating in the mannerafnd for thelpurposes set fol-tb.

3. The arrangement of the slides F, sheaves d all d2, and cords e e, with the frames A A and bows a a, as I herein set forth. I In testimony that I claim the foregoing I have hereunto set my hand this12th day of April, 1867.
